WebJun 5, 2016 · Clockwise variants of lower loop reentry have also been described. The true prevalence of lower loop reentry is uncertain as the ECG morphology can be indistinguishable from typical flutter and termination occurs with CTI ablation. It is therefore possibly more common than diagnosed. WebHowever, lower loop reentry was confirmed in only 3 of 10, and none of the 3 lateral wall circuits were present.
